超电流:AdS黑洞的矢量头发

Supercurrent: Vector Hair for an AdS Black Hole

Pallab Basu, Anindya Mukherjee, Hsien-Hang Shieh

摘要:

在arXiv:0803.3295 [hep-th]中,讨论了全息黑洞解,其表现出类似超导体的转变。在超导相中,黑洞表现出无限的直流电导率。这就产生了在没有任何电场的情况下,通过打开与时间无关的电流(超电流)使溶液变形的可能性。由于无毛定理,这种类型的变形对于正常(非超导)黑洞是不存在的。本文研究了这种超导溶液及其相图。有趣的是,我们在相图中发现了一个“特殊点”(临界点),在那里二阶超导相变变为一阶。超导材料中的超电流是凝聚态系统中的一个研究得很好的现象。我们发现一些定性的协议与已知的结果。

英文摘要:

In arXiv:0803.3295 [hep-th] a holographic black hole solution is discussed which exhibits a superconductor like transition. In the superconducting phase the black holes show infinite DC conductivity. This gives rise to the possibility of deforming the solutions by turning on a time independent current (supercurrent), without any electric field. This type of deformation does not exist for normal (non-superconducting) black holes, due to the no-hair theorems. In this paper we have studied such a supercurrent solution and the associated phase diagram. Interestingly, we have found a "special point" (critical point) in the phase diagram where the second order superconducting phase transition becomes first order. Supercurrent in superconducting materials is a well studied phenomenon in condensed matter systems. We have found some qualitative agreement with known results.
